4.1.10 Strobe and Constant (dc) Modes: The strobe mode is used

to“freeze”amovingitemataparticularmomentintime.Typically,with

LED illumination sources, the strobe mode involves driving the light head

with a high current, short duration pulse. This provides a very intense light

output pulse. As long as the duty cycle is kept short, no damage to the

LEDs occur as a result of the high current. Where a non-moving object is

to be viewed, the constant mode is used. The light is simply turned on and

left on for as long as desired. In this mode the drive current is a fraction

of that used in the strobe mode. The Pulsar 710 limits this current to a

levelwherethelightheadcanbeoperatedindenitelywithoutdamage.

4.1.11 Timing Bypass: This is a strobing function with high output power

that allows the Pulsar 710 to track the pulse width of the input trigger

pulse. This function is not to be confused with gated DC mode. It is always

important to remember that Signatech II takes precedence to protect the

connected light head. Therefore, during timing bypass the output pulse

width will only track the trigger signal until the maximum allowed pulse

width for the selected current is reached. After this point, increasing the

trigger pulse width will have no effect on light head output.

4.1.12 Trigger: The signal which initiates an output from the Pulsar 710

to the light head. The trigger signal is normally generated by an external

source such as a camera or other sensor. Several modes of trigger

operation are provided for in the Pulsar 710. The trigger may start on

either a rising or falling edge. For test purposes, the Pulsar 710 also has

an internal trigger source.

4.1.13 Trigger Pass Through: Also known as “loop through,” this

feature allows several controllers to be driven simultaneously by the

sametriggersource.Tominimizelatencyofthetriggerpassthrough,the

trigger input and output are not buffered. This looped through signal is

then daisy chained to a second controller or device. The purpose is to

minimizeanydelaybetweenthetimetherstcontrollerinthechainand

succeeding controllers receive the trigger signal. To enable this feature

refer to Appendix “C”.

4.1.14 Trigger Delay:Certainapplicationsrequirethataknown,xed

time elapse between the receipt of a trigger signal and the initiation of

an output pulse. This is the trigger delay. For example, if the trigger signal
